How To Test a Watch Using Calypso Waterproof Tester

A simple guide how to use a pressure tester and how to test the waterproofness of a watch.
The pressure gauge on the tester shows the unit: 1kg/sq cm ≈ 0.98 bar, 1MPa = 10 bar.
This particular watch I will test to 3 bar = 3ATM = 30M
I use only distilled water to prevents mineral deposits building up in the tester.
Step 1: Fill the chamber with
Step 2: Hang the watch and close the lid tight
Step 3: Pressurize the chamber to the target pressure
Step 4: Wait 3 minutes and lower the watch in to the water
Step 5: Slowly release all air
Step 6: Look carefully to the bubbles

Besides the bubbles rising to the surface of the water I still don’t understand what point do you take to know that water doesn’t get inside the Watch ? Thank you for sharing.

[@MagicWatchmaking]

The bubbles are just air underneath the bezel. Important is no bubbles from crystal, crown or case back.
Thank you for watching ☺️

[@WatchWithMike]

I would've been less nervous if you tested the case without the movement! 😁

[@MagicWatchmaking]

No risk, no fun 🤗

[@WatchWithMike]

@@MagicWatchmaking lol, fair enough! Sounds 😁

[@g0ral]

Can you measure divers up to 200m in this chamber?

[@MagicWatchmaking]

With this chamber not! This can measure 60m maximum.

[@selkiemaine]

I'm assuming that the bubbles mean that the watch failed the test. Oh well - it is an old watch.
